The relationship between the full angular width at half maximum intensity of central bright fringe versus wavelength, width of planar waveguide and relative refractive index of waveguide was presented too. 给出中央亮条纹强度半最大值全角宽度与工作波长、波导宽度和波导相对折射率关系曲线。
The experimental results showed that the full width of half maximum of resonance spectrum is proportional to the electron density, namely the full width of half maximum become wider with the electron density increased. 从实验结果中可以看出,共振谱的半高宽与电子密度成正比,即电子密度越大,半高宽越宽。
